What Are You Doing To Prevent Wrinkles (If Anything)?

Is the fact that it's about to be the year 2011 making any of you feel a little ... old? I'm feeling positively ancient. So I think we should chat about what weapons you guys have been employing (or not) in the war against wrinkles.

My anti-wrinkle measures aren't as proactive as I'd like; I really should be using a night cream with retinol--or better yet, a prescription-strength retinoid--since that's the ingredient every single dermatologist I interview touts as the most-proven anti-ager out there to date. But I usually react sensitively to such products and quickly abandon them. So for now, I rely on a daily moisturizer with broad-spectrum sunscreen and a good eye cream to help me push back the onset of wrinkles. Oh, and I have a cute dog (apparently those prevent wrinkles, too!).

How about you guys: How old are you, and what (if anything) are you doing to prevent wrinkles? Do you use an eye cream that has anti-aging effects? A retinol face treatment? Sunscreen every single day? Have any of you already tried something more extreme, like Botox?
